Note 62 — Chapter VIII · ANALYTICA POSTERIORA II.
Reading edition
Analyt. Post. II. xix. p. 99, b. 15-19: περὶ μὲν οὖν συλλογισμοῦ καὶ ἀποδείξεως, τί τε ἑκάτερόν ἐστι καὶ πῶς γίνεται, φανερόν, ἅμα δὲ καὶ περὶ ἐπιστήμης ἀποδεικτικῆς· ταὐτὸν γάρ ἐστιν. περὶ δὲ τῶν ἀρχῶν, πῶς τε γίνονται γνώριμοι, καὶ τίς ἡ γνωρίζουσα ἕξις, ἐντεῦθέν ἐστι δῆλον προαπορήσασι πρῶτον.
Bekker and Waitz, in their editions, include all these words in ch. xix.: the older editions placed the words preceding περὶ δὲ in ch. xviii. Zabarella observes the transition to a new subject (Comm. ad Analyt. Post. II. ch. xv. p. 640):— “Postremum hoc caput (beginning at περὶ δὲ) extra primariam tractationem positum esse manifestum est: quum præcesserit epilogus respondens proœmio quod legitur in initio primi libri Priorum Analyticorum.”
